+.Sh NAME
+.Nm fdcontrol
+.Nd modify floppy disk parameters
+.Sh SYNOPSIS
+.Nm fdcontrol
+.Op Fl d Ar 0|1
+.Ar device
+.Nm fdcontrol
+.Op Fl s
+.Ar device
+.Sh DESCRIPTION
+.Nm Fdcontrol
+allows the modification of the run-time behaviour of the floppy
+disk device specifed by
+.Ar device .
+.Ar Device
+should be a character device.
+
+.Nm Fdcontrol
+currently supports the specification of device parameters for the
+floppy disk drive
+.Po
+.Fl s ,
+also default mode
+.Pc ,
+or it allows the modification of the driver debug level, in case the
+floppy driver has been compiled into the kernel with the
+.Em DEBUG
+option set
+.Pq Fl d .
+
+Since the implications of such actions are considered harmful, the
+underlying
+.Xr ioctl 2
+command is restricted to the super-user.
+
+When requesting a new parameter specification, the command asks the
+user for each individual tunable parameter, defaulting to the
+currently used value.
+
+.Sh DIAGNOSTICS
+Error codes for the underlying
+.Xr ioctl 2
+commands are printed by the
+.Xr perror 3
+facility.
+
+.Sh BUGS
+The
+.Nm
+command is currently under development. It's user interface is rather
+silly and likely to change in future, options should be provided to
+allow anything being modified from the command line.
+
+The driver does actually support only two debug levels
+.Pq 0 and 1 ,
+where debug level 1 will generate huge amounts of output. It is likely
+to overflow the syslog if not used with extreme care.
+
+.Sh SEE ALSO
+.Xr fdc 4 ,
+.Xr ioctl 2 ,
+.Xr perror 3 .
+.Sh HISTORY
+.Nm Fdcontrol
+is currently under development. It's user interface and overall
+functionality are subjects to future improvements and changes.
+.Sh AUTHOR
+The program has been contributed by
+.if n Joerg Wunsch,
+.if t J\(:org Wunsch,
+Dresden.
